Hi,
I have gone forward and winterized my returns and pump/filter with no problem, but when trying to blow out the main bottom drain, my wet vac doesn't have enough blower pressure to overcome the water pressure of the pool (probably about 6' deep now that it's lowered = 2.6 psi) . I poured about a gallon of pool antifreeze down the drain line, but I can still see the water level slightly below ground when I look down the pipe, so my water/antifreeze mixture is not below frost line. I don't have a valve on the return drain line to airlock, although I suppose I could cut the PVC and add one on.
Will the water/antifreeze mix be okay or do I need to do something else?
Thanks,
